BMW N5X Oil Funnel

Use case:

I found it rather annoying and hard to not make a spill while adding oil to my Z4 with the N54TU engine. There's not enough room to maneuver an oil container without making a small spill.

This should help resolve this issue. I added inserts and a rim to fit in the oil fill. This should keep the funnel stable while adding oil during oil changes. I also added a rim on top of the funnel to effectively reduce spill-backs.

Funnel measurements:

Funnel entry diameter: 123mm OD / 110mm ID
Funnel exit diameter: 38mm
Insert to insert distance: 51mm
